120 hz TV as a Computer Monitor?

[Wolfmeister1010]

So, my TV that I ordered, the LG Electronics 47LB5900 47-Inch 1080p 120Hz LED TV, http://www.amazon.com/Electronics-47LB5900-47-Inch-1080p-12Hz/forum/Fx3EWDDDQ18KKAH/-/2/ref=cm_cd_ql_psf_ql_next?_encoding=UTF8&asin=B00KVLT0HM&cdAnchor=B00KVLT0HM&cdSort=best

is supported by an HDMI cable, but says that it runs at 120 hz NATIVELY, with an ability to reach 240 through some clearscan thing.

My question is, if I hook up the PC to the TV via HDMI, should I theoretically be able to still have it set to 120 hz? Or will it automatically go to 60, since it is connected to a PC?

Your video card will determine the refresh rate and Windows should recognize your TV.

It'll only support 60hz on a pc because graphics cards still only have hdmi 1.4.

what do i need to pull 120 hz on tv then what about dvi plugs what if my tv has for dvi and hdmi?

It still might not work as the tv may just be interpolating. Assuming it's not, then hopefully it's dual link dvi and will work just fine.

'Active' DVI-D or (mini-)Displayport to HDMI 2 ...

It is highly likely that your TV input is HDMI 1.4 -- not HDMI 2, and I'll guess there is no DVI or Displayport input.

It's possible the HDMI 1.4 port could be updated to HDMI 2 via firmware, but I suspect most OEMs will only provide this option for 'fancy' 4K models purchased by early adopters.
